COVER-MOLD.

Patented Jan.25, 1916.

Original application filed February 25, 1915, Serial No. 10,594.Dividedand. this application filed May 13,

1915. Serial No. 27,905.

To all whom it may concern:

Be it known that 1, WILLIAM G. LERCH, a citizen of the United States,residing at Easton, in the county of Northampton and 5 State ofPennsylvania, have invented a new and useful Cover-Mold, of which thefollowing is a specification.

The devic forming the subject matter of this application is a mold inwhich may be formed a cover of that sort which is used in connectionwith concrete burial vaults.

This application sets forth matter divided out of my co-pendingapplication for Letters Patent on a concrete burial vault Serial No.10,594, filed February 25, 1915.

Oneobject of the invention is to provide a device of this type embodyinga novel form of core which may be removed readily from the finishedproduct and from the supporting frame wherewith the core is assembled.

Another object of the invention is to provide novel means for retainingthe aggregate in place adjacent the ends of the mold o and to providemeans whereby the aggregate may be shaped properly to form the outerface of the finished cover.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, th invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of. theinvention.

In the accompanying drawing :-Figure 1 shows the invention in top plan;Fig. 2 is a longitudinal section; Fig. 3 is a cross section; Fig. 4 is afragmental perspective delineating a part of the lid or cover which isfashioned in the mold constituting the subject matter of thisapplication.

As shown in Fig. 4 of the drawings, the mold constituting the subjectmatter of this application is adapted to be employed for fashioning acover or lid T, the same including a rim C, the upper peripheral edgesof the cover T being rounded as indicated at E. If desired, handles 101of any deslred sort may be assembled with the cover.

The mold in which the cover T is formed, comprises a base of rectangularoutline and provided with a rectangular opening 26. The base 25 isequipped with an upstanding marginal rim 29, defining a recess 30. Thecore comprises a central member 28 in the form of a truncated triangleand a pair of end members 31, the end members 31 being inclined alongtheir inner edges to coact with the inclined edges of the central member28 of the core, the inclined edges of the members 31 being indicated at102. Fixed to and depending from the central member 28 of the core is aflange 27, received closely in the opening 26 to prevent relativemovement between the central member of the core and the base 25. The endmembers 31 of the core rest upon the end portions of the base 5. Mountedupon the ends of the base 25 and overhanging the recess are plates 32held in place by means of securing elements 33 which may be pins or setscrews. The plates 32 are rounded as shown at 34.

When the core forming parts 28 and 31 are in position as shown in Figs.1 and 2, the aggregate is placed on the core and is compacted beneaththe plates 32. A straight edge 100 is slid along the upper edges of theplates 32 and is made to traverse the rounded end portions 34 of theplates. By this operation, the upper face of the cover T is smoothed ortroweled off and the rounded edges E are produced, the handles 101 beinginserted before the constituent material of the cover has taken a finalset. In the recess 30 formed by the rim 29 and the edge of the core28-31 the depending rim C of the cover T is fashioned. The plates 32serve to prevent the aggregate from flowing endwise off the mold andalso, as hereinafter stated, act as guides for the straight edge 100.

It will be understood, without specific illustration, that if desired,the cover T may be reinforced in any desired manner, as is the commonpractice of those skilled in the art.

In practical operation, after the product has been finished, the endplates 32 are removed, and the core sections 28 and 31 are detachedfrom. the product, the specific construction of the core involving theblunted triangular section 28 and the complemental sections 31,facilitating such an operatiom' Having thus described the invention,What is claimed is 1. A cover mold including a base having an opening; acore comprising a central section having a flange engaged Within theopening, and end sections cooperating with the central section, thecentral section being in the'form of a blunted triangle, and thetransverse edges of the end sections being inclined to cooperate Withthe transverse edges of the central section.

2. In a cover mold, a bed having an opening; a core supported by the bedand provided with a projection received in the open ing; and end platesdetachably assembled with the bed, the end plates constituting straightedge guides, and the extremities of the end plates being free andexposed.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two Witnesses.
